Start with the small triangle on the right:
35 + 96 + x = 180
x = 49
Ah, you already have that. Nice!
Now move to the biggest triangle:
x + 77 + (35+y) = 180
but x = 49, so
49 + 77 + 35+y = 180
y = 19
You add 1/4 each year:
800 to 1000 in one year
1000 to 1250 in 2
1250 to around 1812.5
Answer:

Step-by-step explanation:
The formula for this equation is

a is the final result
p is the starting amount (deposited)
r is the interest rate
n is the number of times it's compounded
t is the time
because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117
Please double check me I may be wrong, this is my second time doing these type of questions
The equation is 10x=y I’m not sure how we’re supposed to show a graph over this app
